Description
Technical field
The invention belongs to fermentation technical fields, and in particular to a kind of fermentation medium and zymotechnique of kasugarnycin.
Background technique
Kasugarnycin (Kasugamycin) belongs to produced by springtime streptomycete (Streptomyces kasugaensis)
Aminoglycoside antibiotics finds that it is also known as kasugarnycins from Nara County, Japan springtime sacrificial place in April, 1964 within the border.China
It was also separated to one plant of kasugarnycin producing strains from the Jiangxi good area of soil in 1963, with Japanese strain in utilization of carbon source and various trainings
Supporting cultural characteristic on base has many differences, therefore is named as streptomyces microaureus (S. microaureus).
Kasugarnycin has just been widely used in agricultural since research and development, in Asia and South America.It is to rice blast
The prevention and treatment of (including leaf pest, rice head pest, paddy pest) etc. is especially pronounced, generally can reach 80% or more.Moreover, kasugarnycin
Applicable crops further include potato, cucumber, celery, sorghum, capsicum, Kidney bean, citrus etc., can prevent and treat the raw tail of beet on beet
Carrot soft gull Wen bacterium on spore, potato, the Kidney bean pseudomonas that dwells on Kidney bean, the pseudomonas that sheds tears on cucumber, kind
Eggplant leaf mold, cucumber bacterial angular leaf spot etc..
It is noted that meeting modern environmental requirement, by because kasugarnycin is nontoxic to people and animals, noresidue, pollution-free
State's green foods development center is recommended as AA grades of pollution-free food production data, is classified as Agricultural product without pollution by the Ministry of Agriculture and recommends
Pesticide is classified as Vegetable Standardization engineering by Shanghai City and first elects fungicide.With the raising that people realize chemistry security, spring thunder is mould
Plain efficient, wide spectrum, non-harmful biological nature illustrate more and more extensive market prospects.Since it has significant anti-plant
Disease fungus activity, therefore be successfully just agriculturally widely used from formulating.Its low toxicity, it is mesh that safety is efficiently, environmentally friendly
Has pesticide with broad prospects for development in one of the environment friendly agricultural of preceding most promotion prospect, and current crop pest control
One of.
Currently, the fermenting and producing of domestic kasugarnycin uses three grade fermemtation mode, main problem existing for which have with
Lower several points:
